Buy it here: Stop staring at my light saber short
The "badass" description of the light sword above is only true in the movie parts of Star Wars. But with the speed of development of technology today, the application of Lightsaber is probably only a matter of time.
For example, theoretical physicist Michio Kaku used a heat-resistant porcelain up to 2,000 degrees Celsius to make a blade, with holes in the surface that allowed plasma to escape. His hilt is equipped with carbon nanotubes that are very small in diameter, only 1 / 20,000 hairs and act as electrodes in nano batteries. With billions of billions of nano panels, we can easily generate about 15 mega watts of electricity, enough to produce plasma blades while keeping the grip size compact.
